Application filed January 80, 1905. Serial No. 243,250.

To (all 1,071,071] 7'2; ntrty (ton/Porn:

lilo it known that 1, CHARLES Dianna, a oitizon of tho Unitod States, and a rosidont of tho oity ot Now York, borough oil Briwlrlyn, in tho oounty of Kings and E'itato of Now York, havo invontod a now and l niprowd flaw-Mot, of which tho following is full, oloar, and exact dosoripthin.

Tho purposo o'li tho invontion to provide a simple, ooonon'iio, and o'll'ootivo saw sot :ulaptod 'lt'or uso in oonnootion with any charaotor of saw, ono which can bo oon'voniontly opoii'atod and which will hav'o a hannnor aotion, onabling tho tooth oi the saw to bo sot as mcuratoly and roadilyoutsi do ot tho shop as at a bonoh within tho shop.

fl. turthor purposo of tho inwntion is to provido a light tool which can be roadily oar- .riod in a tool ohost or bag and which is always roady tor uso, having no parts liablo to booolno soparatod and lost.

'lho invontion consists in tho novol coir struotion and combination o'l tho sovoral parts, as will bo lunroinaxltor iiully sot forth, and pointod out in tho olailns.

lto'lioronoo is to ho had to tho aooolnpanying drawings, Forming a part of this spooilioation, in whioh similar oharzuztors oi ij'otoronoo iru'lioato oorrospoluling parts in all tho lig- 'uros.

l iguro l is 2 plan viow of tho iinprovial too]. Fig. 2 is a longitmlhntl sootion talion praotivally on tho lino 2 2 of Fig. 1. Fig. 3 is a sido olovation 0t tho dovioo, illustrating its oonstriuztion for heavy work; and Fig. 4-.

is a plan viow of tho dovioo shown in Fig. 3.

'lho hoad A o't tho tool. :is of skoloton 'lor ination, boin g proforably somewhat oval. Tho onds l0, howovor, aro givon mom or of an upward ourvo, and said hoad is doopost at its tront and roar sido portions ll and 12, as shown in Fig. 2. A vortioal roooss 13 is inado in tho innor tfaco of tho TEl'Olll) oontral portiol'l oi. tho hoad, adaptod to roooivo a roniovablo anvil-block 14 whoso lowor ond is downwardly and outwardly bovolod from its innor iaoo, as is shown at 15 in Fig. 2. The

anvil-blook is hold in place by attaohing thoroto a threaded ston]. 1'7, which passos out through an oponing 18 in tho iiront portion ll of tho hoad. having a thumb-nut 19 and washor a ipliod to its nrojooting ond, as is also shown in Fig. 2.

A. tubular handlo 20 is attaohod to or is niado intogral with. tho 3. :ar oontral portion of tho hoad A, boing sopz'lratod by a partition 21. into a :l orwa rd chamber 22 and a longor roar ohainbor Q3. Tho ohalnbor 22 is opon at tho top; but tho roar chamber 2?) {)litGthfiitlljf olosod, oxoopt that an opening 24; is produood at its outor ond andv a longitudinal slot 25 is niado in its uppor iliaoo., l n prot'orably tho right-initial wall of tho said slot ono or niol'o rooossos, )i 'oilorably two, 26 and 27, aro 'l orniod.

An upwardly and roarwardly iuolinod jaw 28 is inl'iroduood into tho hoad A from tho bottom, having a V-slot 12$) in its uppor odgo, and whon tho jaw as is in position tho slot 29 is opposito tho straight innor iiaoo of tho an- 'il-loloolc 14-. Tho jaw 28, 'whioh sorvos as a guido for tho blado 2-30 of tho saw, is adjusts ably hold in position by forming a roar- \\'ardly oxtonding link 31 at its bottom, through 'whioh link a sot-sorow 32 is passod into tho handlo.

In tho roar sido portion 12 of tho hoad A a rootangular oponing 33 is produrml, whivh is in lougitlulinal alinoinont with tho anvilblook H, and a oorrospoiuling oponing Ill is produood in tho partition 21, whioh .lattor oponing is by pro'l oromto oiroular. A sotting-- bar 1 has sliding niovonlont in tho two oponings 33 and 34-, tho TFUIWVttl'll portion 35 oi the said sotting-bar boing 'n'ol'orabl y rootangular in oross-sootion, so that it oannot turn in tho oponing 33, and whon tho sotting bar is in position its innor ond has :liroo play in tho oponing 34: in tho partition 21, and its torward ond has froo niovonunit in tho oponing 33 in. tho head, and tho striking or outer ond of tho sotting-bar will pass through tho slot in tho jaw 28 and will ho in position when torood forward to striko against tho anvilblook l-il or the tooth of a saw hold botwoon tho slottod. portion of tho aw 28 and the said anvil-block, as is illustratod in Fig. 2. The sotting-bar is normally hold away from the anvil-block 14 by means of a spring 36, located in the chamber 22 of the handle, which spring is coiled around the said setting-bar and has bearing against the head at one end and against a pin 3'? at its opposite end, which pin is passed through the setting-bar. The setting-bar is adapted to be struck at its rear end by a hammer 38, which hammer is also in the form of a bar and is located in the longer chamber 23 of the handle. The outer end of the hammer 38 extends out through the end opening 2st in the handle.

The hammer 38 is provided with an attached post 39, and this post extends out through the slot in the top of the handle and is capable of being carried from end to end of the said slot and also of being made to enter either of the recesses 26 and 27. A spring 1L0 ,is coiled around the hammer 38, having bearing against the post or stud 39 at its forward end and against the rear end wall of the said chamber at its opposite end, as is also shown in Fig. Normally the forward end of the hammer 38 is in engagement with the rear end of the setting-bar B. After the saw has been placed between the jaw 28 and the anvil-block with a tooth opposite the slot 29 in the aw, the aw is adjusted forward and locked so as to hold the saw in its adjusted position. The hammer 38 is then drawn back by carrying the stud 39 to the rear portion of the slot and until the setting blow is to be given the hammer can be held in its rear or striking position by carrying the stud 39 into either the recess 26 or the recess 27, according to the force of the blow required. As soon as the post 39 is placed in position to slide in the slot and is released, the spring l0, which had been placed under tension, will force the hammer forwardly and cause it to strike more or less forcibly against the rear end of the settingbar, driving the forward end of the latter with more or less force in contact with the tooth to be set.

I desire it to be understood that the spring 40 may be more or less strong, and if said spring is exceptionally strong I contemplate the use of a lever suitably applied for setting the hammer or placing it under tension, the said lever being a substitute for the post 39. Such a construction I have shown in Figs. 3 and 4:, wherein it will be observed that the slot 25 is omitted from the handle 20, and in its stead a straight longitudinal slot ll is produced in one side, and the spring %0 of the hammer 38 does not bear against a vertical pin 39, but against a horizontal pin H), which extends out through the slot 41, being provided with a friction-roller 47 at its outer end. At each side of the outer end portion of the handle 20 parallel and vertically-disposed bearings 5 2 are produced, and a short shaft i3 is journaled in the upper portions of said bearings. At one end of the shaft l3 a gear-wheel 4A is secured, and a lever 2L5 is attached to the gear, whereby the gear may be turned by hand. The friction-roller 47 has bearing against the convexed rear edge of a segmental bar &8, located at the opposite side of the handle to that bearing the gear 44, and the lower end of the segmental bar A8 is secured to a shaft 49, journaled in bearings 50 at the under side of the handle 20. A pinion 51 is fastened at the opposite end of the shaft 49, meshing with the gear-wheel it. Thus in operation by moving the handlever A5 in one direction by means of the gear ll and pinion .51 the segmental bar 48 is rocked toward the inner end of the handle 20, and by constant engagement with the friction-roller 47 the said bar 4E8 at such time forces the hammer 38 in the same direction, placing the spring L0 under compression, and as soon as the hand-lever 5L5 is released the said spring +t0 acts to carry the hammer to its normal position and to a forcible contact with the setting-bar B.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. In a saw-set, a head and a handle therefor, the head being provided with an anvil and with an adjustable jaw, a setting-bar having end movement partially in the head and partially in the handle, the end of the setting-bar in the head being opposite the anvil, a hammer having end movement in the handle, means for locking the hammer temporarily in a rear or striking position, and means for forcibly carrying the hammer to contact with the setting-bar when the hammer carried from its striking position.

2. A saw-set, comprising a head having an anvil-block and a slotted jaw, a tubular handle forming a portion of the head, a springcontrolled setting-bar having end movement in the handle and in the head, the end of the bar in the head being opposite the said anvilblock and the slot in the jaw, normally passing through the latter, a spring-controlled hammer having end movement in the handle, and means for locking the hammer in temporary position under the tension of the spring.

3. A saw-set, comprising a skeleton head, a tubular handle forming a portion of the head, an anvil-block located in the head, a slotted jaw located opposite the anvil-block, a spring controlled setting bar having guided end movement partially in the handle and partially in the head, the end of the setting-bar in the head being opposite the slot in the jaw and opposite the anvil, the handle being provided at the rear of the setting-bar with a longitudinal slot having recesses in one of its walls, a hammer having end movement in the said handle, one end of said hammer being nornlally in eligag'emeilt with the rear end of the setting bair, a pest extending; from the hammer through the slot in the handle, and a spring coiled around said hammer between the post and the end of the handle.

l. A. saw-set, con'iprising a head, a tubular handle secured to the head and having a longitudinal. slot, an anvil carried by the head, a, jaw also caried by the head, opp( site the anvil, a spring-pressed setting-bar having end movement in the head and handle, and a sliding and spring-pressed hammer in the tubular handle and having a member projecting through the slot of the handle to permit the hammer to be moved against the tension ol? the spring.

5. 'ln a saw-set, a head, a, handle seemed to the head and provided with two chambers one in the rear of the other the :lbrWard clnnnber being open. at [he lop and the rear one provided with a longitudinal slot, an. anvil carried by the head, a slotted ja I also carried by the head, opposite the anvil, a HPI'illg-lDl'USSQCl setting-bi mounted in the 'liorward chamber with ends projecting through the end walls of the chan'iber, a hammer in the rear chamber of the handle and provider l with a pin projecting through the slot of the said chamber, and a spring coiled on the rod between one end Oili' the chamber and the said pin.

In testimony whereot l have signed my name to this specification in the presence oil? two subsmribin witnesses.
